hello:
now our plant plan to replace oil analysis supplier,so we choose two suppliers and sample the same oil, but the result from two company is different, including Viscosity、TAN、Moisture and additive element,just PQ indicator is the same.
I am not sure if there are some tolerance for oil analysis or not? if so, what's the standard we can accept?
